Correct, 30F. Camping on an island where we canoe to - so no car.
I ended up getting an off brand sleeping pad but it has great reviews and people said it held up during the cold... Had to buy one that would get shipped in a day or 2 due to my trip coming up soon - https://www.amazon.com/gp/product/B09YV1CBQM/
Then ended up getting this sleeping bag - https://www.amazon.com/gp/product/B001D6MF26/
We'll see how they hold up. Appreciate the info - if these don't hold up this trip - I'll end up investing in a name brand one off the website you posted.
